Brain electrical activity can stop completely, or drop to such a low level as to be undetectable with most equipment. See also H. Tristram Englehardt, Jr., Defining Death: A Philosophical Problem for Medicine and Law, 112 Ann. The most common type of death is the first one, in which the heart has stopped beating and/or the patient is no longer breathing (usually followed by brain death). Janet Levin, Functionalism, The Stanford Encyclopedia of Philosophy, http://plato.stanford.edu/archives/fall2013/entries/functionalism/ (last accessed Oct. 17, 2016). This also help clears up some of the conceptual confusion as to whether such operations would be ‘head transplants’ or ‘body transplants’.55 If the brain is in some way what matters, then what matters in such a transplant is the head, not the body. But sometimes (as in the second definition), an individual may be kept "alive" through the use of ventilators and feeding tubes even though there is zero brain activity. While the death criteria trifecta currently suffice, they will not permanently be sufficient for determining death. The Trump Administration’s Flawed Decision on coronavirus Vaccine Injury Compensation: Recommendations for Changes, Transparency too little, too late? While the diagnosis of brain death has become accepted as a basis for the certification of death for legal purposes, it is a very different state from biological death - the state universally recognized and understood as death.

This means they will not regain consciousness or be able to breathe without support. 90, 26:6A–5 (1991). While the enormous need for organs does not influence the truth of the matters as to what we value in persons or what constitutes death, our legal and social institutions must take the need for organs into account in developing beneficent social policy. In the wake of the 1976 Karen Ann Quinlan case, state legislatures in the United States moved to accept brain death as an acceptable indication of death. It is the complete stopping of all brain function and cannot be reversed. It's generally caused by blunt head trauma from accidents, falls, or crush injuries; thrombotic or hemorrhagic stroke, especially when the infarct causes brain herniation; or an anoxic injury that causes the death of brain cells that don't regenerate. As James Bernat has argued, neurological criteria currently represent optimum policy as they encompass ‘the critical functions of the organism as a whole’.53. These definitions include historical and current standards, but also proposed alternative standards. The value for the EEG test is reported as "53-80, 4/97". holds that individuals are dead when they have irreversibly lost all higher functions of the brain (usually defined as all capacity for consciousness) An answer to this question will consist of a definition (or conceptualization).  For children and adults, testing is optional. Incorporating the cardiopulmonary test thus allows the traditional medical standards to continue to operate, so that doctors need not do an EEG before issuing a death certificate in every individual case. Indeed, in 2008 the President's Council on Bioethics went so far as to advocate for a ‘total brain failure/standard as opposed to the total brain death standard, in part for measurement reasons.52 However, given the current medical technology available, it seems that neurological criteria represent the most pragmatic set of standards for what constitutes death. traumatic brain injury, intracranial haemorrhage, hypoxic encephalopathy) consistent with the irreversible loss of neurological function. This hormone is produced to concentrate the urine in the kidneys, thus protecting against life-threatening dehydration. In the vast majority of cases, traditional cardiopulmonary standards for death will be sufficient.49 Furthermore, as the Commission noted in its Defining Death report, ‘The [total] brain-based standard is after all, merely supplementary to the older [cardiopulmonary] standard, which will continue to be adequate in the overwhelming majority of cases in the foreseeable future’.50 Indeed, it will be in the hard cases that a brain-based standard becomes necessary.

Smart, The Mind/Brain Identity Theory, The Stanford Encyclopedia of Philosophy, http://plato.stanford.edu/archives/win2014/entries/mind-identity/ (last accessed Oct. 17, 2016). A single set of standards for death pronouncements is appropriate for all legal purposes (encompassing inheritance, taxes and criminal trials, as well as medical treatment). As the Commission notes: “the traditional “vital signs” of heartbeat and respiration were merely surrogate signs with no significance in themselves.24 On this view, the heart and lungs are not important as basic prerequisites to continued life but rather because the irreversible cessation of their functions shows that the brain had ceased functioning.”25 Insofar as the traditional criteria indicated the change that really mattered, they were helpful in determining death. Finally, in Section IV, I explore ways of synthesizing our definitions of death with what we care about.
